News reports on 22 October highlighted the exercise as a symbol of deepening defence ties between India and Japan.
Background
JAIMEX is a bilateral maritime exercise conducted by the Indian Navy and the Japan Maritime Self‑Defense Force (JMSDF). It aims to enhance interoperability, practice complex naval manoeuvres and strengthen maritime cooperation under the India–Japan Special Strategic and Global Partnership established in 2014. INS Sahyadri, commissioned in 2012, is an indigenously built multi‑role frigate capable of anti‑air, anti‑surface and anti‑submarine warfare. Japan’s participants included the destroyer Asahi, the replenishment ship Oumi and the submarine Jinryu.
Exercise highlights
- Sea phase: Conducted in the western Pacific from 16–18 October 2025, the sea phase included anti‑submarine warfare drills, missile defence exercises, cross‑deck helicopter operations, underway replenishment and coordinated manoeuvres. These activities improved tactical communication and interoperability.
- Harbour phase: After arriving at Yokosuka on 21 October, the crews engaged in professional exchanges, cross‑deck visits, sports and cultural activities, and joint yoga sessions. Officers also planned future exercises and shared best practices.
- Strategic context: Both navies reaffirmed that the exercise supports a free, open and inclusive Indo‑Pacific. It is part of a broader pattern of joint exercises, including the Malabar multilateral drills with the United States and Australia.
- Indigenous capability: INS Sahyadri’s participation highlights India’s progress towards self‑reliant defence manufacturing under the Aatmanirbhar Bharat initiative.
Significance
- JAIMEX strengthens the maritime partnership between India and Japan, contributing to stability and security in the Indo‑Pacific region.
- Regular exercises enhance interoperability, allowing the two navies to operate together effectively during humanitarian missions, anti‑piracy patrols or regional contingencies.
- It signals to other regional actors that India and Japan are committed to maintaining a rules‑based order and freedom of navigation.
- The exercise promotes defence diplomacy through cultural exchanges, building mutual trust and understanding among sailors.
Conclusion
JAIMEX 25 underscores the evolving strategic partnership between India and Japan. By honing operational skills and fostering camaraderie, the exercise contributes to a safer and more cooperative Indo‑Pacific.
